Hi Anthony, I do not have the code you have reported, but I'm guessing it is to do with the starter signal and has been recorded when the battery failed. I suggest you have the fault code read, identified and then cleared with the use of a diagnostic scan and if it returns the read out will have identified the area of concern, I do not believe the size of the replacement battery is an issue. Regards John

Sounds like when you ran the car out of gas the fuel pump was damaged, these in tank electric fuel pumps are very small and produce allot pressure and volume, the way they do this is to use the gas around them to cool down, when the pump comes out of fuel when the tank is below 1/4 full it starts to get hot very quickly, since your pump was well used (109000 miles) that was the last straw. When you replace the pump also replace the fuel filter.
I would also clean the throttle valve and idle speed control valve, this may be contributing to the low idle complaint, clear the system after the pump and cleaning by disconnecting the battery for a few moments.

Start the engine, and remove the positive cable from the battery, if it stays running your alternator is most likely o.k. because the engine stays running from alternator current once it starts.
I have had 5 of these trucks 1994 to 1997 and I have had to replace many batterys and alternators, and I have even gotten new alternators where the current was not strong enough, that will make the battery light stay on sometimes also.

It sounds like the fuel is not being delivered sufficently to the engine. Try looking here. Perhaps a fuel injecter cleaner (you can pour Seafoam into the gas tank and it is a great fuel injecter cleaner and fuel stabilizer). What did your plugs look like when you replaced them? This can tell you a lot about the combustion chamber. A Haynes manual will be invaluable to you.

SOURCE: 2003 Ford Taurus, 90K, used car, engines shakes, ABS goes on

Are you getting any codes from the Check Engine Light? This sounds like it could have something to do with a sensor. Check your air filter and make sure it's clean. The tach on my 1999 doesn't really work, but it hasn't coincided with other driveability problems. The engine doesn't change in it's RPM's, the tachometer just stops working. Have your charging system checked. The shaking might be coming from bad fuel pump operation, clogged fuel filter, or dirty fuel injectors. Try putting an additive into your gastank to clean the injectors (a bottle of Seafoam is great for this). Try calling your local Autozone and see if they do free trouble code scanning. This might help lead you in a better direction.

2001 ford Taurus code P1633 what does it mean and how do I fix it ?

P1633 - Keep Alive Power Voltage Too Low

Indicates that the Keep Alive Power (KAPWR) circuit has experienced a power interrupt.

Possible causes:
-Open KAPWR circuit.
-Damaged PCM.
-Intermittent KAPWR Circuit.

First thing would be to check the fuse associated with the KAP. In your case, that would be fuse #22 (10A). If you're A/C doesn't work, then that's why. Usually the A/C clutch causes the fuse to blow and your get your P1633 code.

If the fuse is fine and the A/C works, then it might be a bad PCM. If the battery was bad before it might have set this code. Have you tried clearing the codes to see if it comes back or not?

Hi, i have a problem with my ford escape 2001, check engine with code p1633, what are the cause tank you

Code P1633 simply means that the Keep Alive Power (KAPWR) circuit to the Engine Control Module has been interrupted. This could be due to a dead battery where you had to jump-start your vehicle or because the battery was disconnected for any reason. If your battery is hooked up and in good condition, the code will clear by itself.

It has a cheek enigen on and give the code P1633

When the Taurus PCM (Powertrain Control Module)(aka "the car's computer"), sees 9V DC (or less),
it sets the code P1633, so it means your battery's voltage was low recently. But since the computer
retains the code until it is reset, the battery voltage may be OK now. This is typical for cars
that have sat for awhile, and the tiny current drain of the clock slowly drains the battery until
the voltage drops below 9 Volts. Normal car Battery voltage is 12 Volts.
Fix: check the battery (with a DMM (digital multimeter)), and reset the code (with a code reader).
Workaround: have Advance/Autozone/PepBoys check the battery (free) and ignore the code.

What does the code P1633 mean

P1633 Keep Alive Power Voltage Too Low (Ford/Lincoln/Mercury) It means that at sometime in the past the battery voltage was below specs at the PCM and set the code.The battery provides 12 volts to power everything,the car probably sat for a while and probably took a long time to start or had to be jumped off to start.... when the voltage got below 9 volts it set the code. The code is more of a indicator for info than anything.. the computer learns as you drive and all the code is saying is that it lost it's power to itself and can loose that learned information. Have a shop inspect the battery for being weak or dying as well as your battery connections.. if all is fine, I wouldn't worry. You can have the error reset by a mechanic or auto parts store. If you are paitent enough, the computer will reset itself over time.
